Cutting to the chase: I can't see any 'OK' or 'cancel' button when dealing with the HDR Pro window where you can choose to remove ghosts and everything else. I'm stuck in that window and cannot navigate away without having to force-quit the application. I've downloaded the CS5 Production Premium trial and then, because of this problem, I erased it and installed the Photoshop CS5 Extended trial. All downloaded from Adobe.com. This problem exists on both trials that I have used. I have a mid-2009 2.66GHz MBP.
